Custom properties
Custom properties are the best way to add metadata to SOLIDWORKS models. So we add them to every fastener file.
Custom properties in every file
Every part has the following custom properties:
- Description: a human-readable, useful description of the fastener, its size, material and finish.
- Designation: the name according to the standard
- ISO: the active ISO standard
- DIN withdrawn: whether the DIN standard has been withdrawn. See Supported ISO and DIN standards.
- DIN: the active or withdrawn DIN standard
- Material: the applied SOLIDWORKS material
- Finish: name of the finish or coating
- Mass: weight of the part. The unit depends on your SOLIDWORKS settings.
- IsFastener: if set to one, SOLIDWORKS treats this model as a fastener and shows it as a solid part in a cross-section view.
Specialized custom properties
Threaded fasteners also get thread properties:
- Pitch
- Thread angle
- Tap drill diameter
- Preferred thread
Bolts and nuts get strength properties, when available. We also have special properties for retaining rings, lock washers, screws and set screws.

Change the list of custom properties
Because you own your fasteners, you can always add or remove a custom property.
If you want us to do this for you, we offer Customization services. This service also lets you customize materials, filenames and more.
